Having trouble?
Try selecting the Show Walkable checkbox in the upper left menu to see available points.
Moving times
The estimated time to get from point A to point B is based on the following assumptions:
Human walk speed: 4 feet / sec
Bike speed: 10 feet / sec
Golf cart speed: 8 feet / sec
How it works
To create this application, I took a map of SLU's campus in PDF form and converted it to a large JPG. After this, I went into Adobe Photoshop, and created a layer containing walkable space by filling in the light grey color on the map. I exported this layer as a bitmap. Then, I write a script convert the bitmap to a simple file containing walkable path information with zeroes and ones. My application uses AJAX to validate coordinates, and render the map without reloading the page. Once it finds a path, it simply overlays a transparents GIF with the path highlighted in blue. It uses the A* pathfinding algorithm.
